yesterday i pluged my iphone into a monster cable in the car to charge it. and it asked me if i wanted to turn on airplane mode to reduce interference. i pressed no because i only wanted to charge the phone not play music. so i let it charge only, (no music being played). and after it had charged i unplugged it and went on my way, now at random intervals it asks me wether i want to turn on airplane mode or not, it will ask me mid text or if it is just sitting there at night. and it drains the battery. i tried plugging it back into the cable and unplugging it again but that did nothing, i also cleared all of the memory from the phone and reloaded it with my back up from itunes but it still does this. im so lost at this point, any help would be appreciated.
